Since the creation of green bonds, many new labels have emerged, including social bonds, sustainability bonds, and recently transition bonds, not to mention water, blue or adaptation bonds. Despite the standardisation efforts led by the International Capital Markets Association (ICMA), creativity in self-labelling has increased the number of labels. Whereas the type of activities financed by these various bond labels differ, they are all anchored to the same initial concept and to a pledge by issuers that the proceeds will be dedicated to a predetermined list of eligible projects. These are ‘use-of-proceeds’ bonds.
